To all whom it may concern.'

Be it known that I, HANS voN DEROEL- sNrrz, a citizen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Gas-Aeroplane Motor-Airships, of which the following is a. specification, reference being had therein to the accompanying drawing.

This invention relates to airships and dn'- igihle balloons, and the )rimary object of my invention is to provi e an airshi with planes that will facilitate the guiding of the airship and inci'ease the equilibrium and stability of the same.

Another Vobject of the invention is to provide an airship with -novel ballast tanks that can be easilyV controlled to increase or decrease the amount of ballast and thereby govern the ascent and descent of the airship.

A. further object of the invention is vto provide :in airship of the above type with a novel frame that will add rigidity to .the entire structure, and to so design the frame as to support a plurality of ballonncts.

I attain the above objects by an airship or balloon embodying various instrumentalities which coperate to provide a safe and durable fiying machine that can be used for various purposes, and before describing the construction and operation of these instrumenialities, it' is proper to describe the generaVorganization to which, in the construction of my machine, I prefer to resort.

Primarily there is a strong and rigid frame adapted'to provide compartments for ballonnets, these ballonnetsbeing independent of one another but ,coperating to provide stiflicent lnioyi'mcyfor the fiying machine. The frame of the machine is adapted to support paseuger and engine compartments, and the4 frames forming these compartments are ro- 'vided with landing and cushionings ees adapted to insure a landing of the machine without injnrjtlto the same.. While one of the compartments is designed for passengers, other of the compartments are adapted to contain the power 4bywhich the flying machine is driven and' the operators or crew employed for controlling the machine Vwhen i in flight.

Associated with the foregoing instrumentalities, there are planes located in such a. manner as to facilitate the ascent or descent of the machine and arranged whereby they .can be easil controlled. Besides these planes there are allast tanks, balancing devices, Propellers, and a structure adapted to be used in connection with the flying Inachine for supporting explosives for war purposes, the discharge of the explosives being such as not to nnbalance the machine.

Reference will now be had to the drawings, wherein:

In order that the construction of the flying machine can be fully understood, the structure and the mechanisms will be considered under separate captions and. then the general operation of the mechanisms described. The captions are namely, a frame; ballonnets, Aballast tanks; passenger and engine carriages or com artments; balancing devices; landing an cushioning shoes;

p la'nes; pro ellers and driving mechanism,

thereof, an purposes.

van airsh designed for War Each one o these captions will be considered in detail, and it is thought that then it .will be ap arent that 1 have devised an `airsliip `or ying machine that can be used for pleasure, business or war .1.\\irposes, the entire structure being designed so as to render my machine safe in all kinds of weather, without resorting to devices that will impair the buoyancy and flying qualitic-ations of the machine.

The franw'lhe frame comprises longitudinal main rods 1, 2, and 3. these rods in conjlunction with rods 4 and 5 being ar ranged to form substantially a rectangular structme, said rods.being joined b f connectinfgtiods (i adapted to fo'rm the wa ls or shell o he airship. lThe rods 6 are arranged be# tween the rods 2, 3, 4, and 5 andit is to these (ifi rods that an exterior covering (not shown) can be secured. ,The rods 2`are adapted to be connected tothe rod f1 by'diagonally disosed intersecting trusses 7, these trusses for fini. greater part of their length being" con neet ed to the rod 1. by vertical Vrods 8 and in addition to these trusses additional vertical rodi; 9 are used. The rods 3 are connected td; the rod 1 by similartrusses'and rods, thereli dividing the frame into fourlongitndina- .compartments 10, and thesepoinv pai-tinents are sub-divided from one end of the airship to the opposite end thereof. At the ends of the frame the rods 1 to 4 inclusive are carried beyond the rods-5 to form a nose 11 at each end of the frame, the nose being shapcdby converging the ends of the rods 1 to 4 inclusive and connecting the ends by a nose-piece 19.. stiften the ends of the frame and it is in the nose at each end of the frame that additional compartments are provided. The top of the ptrarne is rounded offl by a roof structure 14 extending from one end of the machine to the opposite end thereof, the roof structure being made of transverse curved rods 14C and longitudinal rods suitably connected togather to provide longitudinal compartments 15.` The frame in its .entirety is made of light and durable metal, for instance aluminum and it is preferable to make all the rods tubular and of double thickness. I accomplish this by makingfthe lrods in sections 19 and 20, with the sections 16) of a greater diameter than the sections 2 0. wheres, by the small sections 20 can be fitted in the4 large sections 19 and thejoints o'r eonf'rontin ends of the sections 19 staggered with re ation to the joints or confronting ends of the sections 20. With the sections 19 and 20 of considerable length I attain a rod that is very rigid and easy to `repair should any part of the rod be bent. various rods it is preferable to use elbows, tees, and specially designed fittings, similar to those used in connecting gas pipes, some of the fittings bein account of the num erof rod connections, and in order that all the rods can be assembled it is preferable to irovide some of the fittings with right-han others with leftdiand screw threads `for the ends of connecting'rods.

Ballonnetaln the compartments 10 of the frame and the compartments 15 of the Tierods 13 are used to In connecting the loo screw vthreads and '1 roof structure are arranged ballonnets 16 and- 17 secured in position by cables 18 or other fastening means. The ballohnets 16 are about the same size throughout, but the sizes of the ballonnet's 17 vary on account of the shape of the roof structure, the'large` .inv the frame the can be varnished and made .Water-proof an l air-tight. By using a'plu rality of these ballornets, I am enabled to retain the airship in the air even though one or more of the ballonnets should bepuncturedor accidentally burst, and it is through this prineiplebf 'distributing the sustaining power of t e machine that I am enabled to i retain the machine-inl the air underthe most A beveled bearing for theA s 4ing a ra id exhaust of ,of the spout -valve in niet decanos trying circumstances. In using the cylindrical ballonnets and arriin 'ng them in tiers, end to end, I um cnab ed to use tie rods, braces and .fi-eines in' addin rigidity to the entire frame, it being possi le to arrange the braces in -tween the tiers and units of the tiers, and it is practically iinpossibleJ to obtain suoli bracing by using spherical ballonnets.

Ballast amica- The` frame of the airship is rovided with two ballast tanks, these tan, s being supported in depending oblong frames 21. carried by the rods 2 and '5 at points aproximately equi-distant from the ends of t e frame and the central portion thereof, the frames beingV constructed of rods similar to those previousl described. In theframes 21 are arrangedI water vtanks 22 made of metal. or a similar material, the top of each tank being flat to rest against the rods 2 and 5, whilet-he bottornof each tank is rounded to avoid any resistance when the flying machine is inated., Extending into each tank is a revoluble shaft 23 and mounted upon said shaft within the tank are spiral agitators 24, these agitators reventing the water ,within the tanks rom freezing. Upon each shaft between the confronting ends of the spiral agitators is a beveled gear wheel .25 and adapted to mesh with said ear wheel is anothergear wheel 26 carried y the upper. end of a. vertical shaft 27 journaled in' a dischar e spout 28 secured centrally of the bottom ogthe tank 22. The spout comprises two tubular sections 29 and 30 connected by a coupling piece or bearing 31,'said coup'lin piece serving as a. central aft 27, while the lower end of the shaft is revolubly supported in a bearin ,32 arranged in the lower end of the tu bullar section 30. Upon the shaft 27Vwithinthe tubular sections 29 and 30 are spiral retarding members 33, these members reventwater when t e lower end of t e outlet structure ,is opened. Connected to the lower end of the tubular seo tion 30 is a valve seat 34 provided with rearwardly extending brackets 35. Connected to th/e coiiplin piece 31 are brackets 36 and 37 and p iv ta connected to the bracket 36 by a pin l3 is t e angularlydisposed arm 39 of avvalv'ular member 40. This" member is provided' with VaresillientA valve 41 adapted to engage the seat 34 and close the lower end `The member 4() is 'provided with deperidin brackets 42 adapted to be connected to t e brackets 35 by retractile spvings 4 3 adapted'rto normally retain the @ritieni .In ,addtien 'iwf' these 'springsfle rackets '37 are provided with coiled springs 44-connected tothe `arm 39, as at45, blow the bracketsf. up. per end` of the' arni 39 isv connected by a cable 46 to a link 47 4adapted yto surround the spodt 28, saidrflink being connected 4to ancarriages-For the tion of these compartments or carriages, r'eference will be had to Figs. 1, 2, 10 and 11. The engine compartments or carriages are at each end of the frame, or 'freight compartment of the airship. Aller these compartments are suitably suspended from the main frame by frames ing frames of the en ine compartments are identical with the. freight compartment, with the exception that the latter is made-of than the former, in order to ture in which'a large number of or. a great amount of freight can e placed. As the sus )eiisioii lframes are identical, I deem it on said frames to Figs. 15 and 16.

Baltinong destaca-In addition to the liquid ballast I use a shiftable ballast of balancing devices that are normally carried b the airship. The balancing devlces are use for maintainin an even keel or in case of emergency, an comprise longitudinally arranged wei bts 49 and transversely arran ed weg ts 50 and 50. The longitudiua y arranged Weights 49 are located between the passenger compartment and the engine compartments andare adapted toI be operated from the engine compartments. The weights 49 are attached to cables 51 passing over sheaves 51l carried by the as' senger compartment, said cables exten ing into the engine com artmentswhereby they can be easil shifte by the operators ofthe airship. T e transverse wei hts 50 and'50 are arranged at'the ends of t e airship and are supported uson cables 52 passing over sheaves 53 carrie by depending bearings 53* of the main frame work of the airship. The cables 52 extend through openings 53 provided therefor in the engine or operating compartment, and these cables as well as the cables 51 are adapted to be manipulated to shift the weights49, 50, and 50* to properl balance the airshl ending and cushionmg shoes-The longitudinal rods 64 forming the side rails of the floor of each carriage frame 54 are provided with tees 65 and mounted in these tees are vertical cylinders 66 having the upper ends thereof provided with ca s 67 supporting tubular guides 68. Slidab y mounted in the guides 68 and extending downwardly through the cylinders 66 and the bottoni of the tees 65 are shoe rods 69, and the lower ends of these rods are connected, as at 70 to longitudinal shoe holders 71. 'The shoehol ers 71 have the sides thereof connected by longitudinal dparallel bars 72, and these bars are adapte to hold resilient 'shoes 73, referabl made of rubber. The bars 72 can e suitab y connected, and the bars u on one side of the frame are connected to t e bars upon the other side by connecting rods 74. T 1e shoes73 having-the upper edges thereof formed :with lateral flangesl 75 ,ada extend over the upper edges Cif/the ars 72, between'the holders 71, while the lower ed es of, the 'shoes are' provided with treads 76. The rods 69 within the rods 66 are provided l with heads 77, and encircling the rodsy 69 between said heads and thecaps 67 are coil springs-,78, these springs being com ressed when `the air-ship is supported by the anding or cqshionir'g shoes.

Planeahe sides ofthe airship a1-eprovided with groups o f Wplanes, onel group of,` planesheng arranged adjacent to the ends" of the airship with the other groups intertoL mediate the ends, each group comprisin posed rods 80. Four rackets are used in connection with each group of planes and the upper and lower brackets are connected by longitudinal'rods 81, and connecting` said rods are vertical bearing rods 82. runnioned between said rods are a plurality of plane frames 83 and these frames are cov-y ered with silk, canvas, or other'material 84. The frames 83 have the longitudinal sides thereof rovded' with lugs 85 having connected t creto endless cables 86, said cables passing u wardly through eyelets 87 provided there or upon a rod 88 connecting the vertical rods 82. The cables 86 pass over sheaves 88* mounted upon shafts 89 journaled in the bearing rods 82 at the lower end of each plane unit. The inner ends of the shafts 89 are rovided with beveled gear wheels 90 me ing with beveled gear wheels 91 mounted upon longitudinal shafts 92, journaled irl* bearings 93 projected from the lower longitudinal rods 4 of the main airship frame. Upon the shafts 99,' are mounted belt wheels 94 over which pass end. less belts 95 that extend through openings 96 in the side Walls of the engine or operating compartments, the belts 95 extend over sheaves 96* journaled in a hanger 97 suspended from the. ceilings of the engine or operating compartments, these hangers being provided with an additional sheave ,98' for a belt 99 adapt-ed to extend overa sheave' 100, carried by the amature shaft of a motor 101 located in the engine or operating compartment at the ends of the airship. The planes located intermediate the ends of the airship can be controlled from the o erating compartmentsfat the end of the airs ip or a motor can be located in the passenger compartment for controllin the intermediate planessimilar toA the'en s planes.

Propellers and #he driving mechanism thereof-The airship at each side thereof and between the planes and the ends fof the to assist -in raising or lowering eitherend of the airshipV andin swinging either 'end t the right or to the left, as occasion ma demand.

'Foursetsof Propellers are use and; arranged the manner above'describd, and as each satis-identical in" construction, I

4 deem it' only necessaryto describe one-'of said- ,plurality of units adapted v f i setsand ,tqrQths purpe 'reference be had' to Fics. 1, '10 and 11. Each set of ropellers embodies a housing 102 supporte by projecting frames 103 f1ern'-the main frame of the airship. AEach housing comprises platforms 104 and 105 and journaled in these platforms are vertical shafts 10G and 107, the shaft 107 being of a greater length than the shaft 106, whereby the lower end thereof will extend downwardly from the platformy 105. The shafts 106 and 107 have the upper and lower ends thereof provided with horizontal propellers 108 employed for raising and lowerinofthe ends of the airship, and the extreme end of the shaft 107 is provided with a belt Wheel 109 for a belt 110 adapted'to extend through an opening 111` provided therefor in the end of the operat ing compartment. The belt 11,0 passes over a belt wheel 112 mounted upon a vertical shaft 113 arranged in the operating compartment and adapted to be driven by a motor or other source of power 114. The motor 114 is employed for operating the horizontal propellers upon both sides of the airship at one end thereof, the belt wheel 112 being double to accommodate the belts 110 extending from each side of the airship. The shafts 106 and 107 are provided with horizontal belt wheels 115 for an endless belt 11G which permits ofthe shafts 106 and 107 being operated in unison. Arranged between the platforms 104 and 105 are vertical posts 117 and revolubly supported by said postsare horizontalV shafts 118 having the outer ends thereof provided with pro ellers 119, While the inner ends are provider with beveled gear wheels 120 meshing with beveled gear wheels 121 mounted upon a vertical shaft 122 jonrnalcd in the platforms 104 and 105. The lower end of the shaft 122 is v rovided with a belt wheel 123 and over said elt Wheel passes a belt 124 which passes through an opening 125 provided therefor in the end of the operating compartment. The belt 124 passes over abelt wheel 126 nimmtcd upon a vertical shaft 127 adapted to be driven by a motor 128 located Within the operating compartment. The propellers 110 are employed for moving the end of theairship either to the right or to the left, and a conventional form of switch or other means (not shown) can be employed for controlling the operationof the motors 114 and 128. ln addition to the propellers just described, I provide each operating compartment with motors 129 for operating propellers 130,

these propellers being employed for moving the airshi back and forth. Besides using the propellers for assisting in the steering and guiding of'theairship, I provide one or both of the operating compartments with rudders. Referring to Figs. 1 and 1,4 it will bc observed that the operating compartment has the end thereof provided with horizontal 'super-imposed frames 131 connected by transverse braces 132 and pivotally mounted between said braces and I intermediate the ends thereof by aT pin 133. is" the rear end rudder 134, the forward end of said rudder having the upper and lower ends thereof provided with guide wheels 135- adapted to engage the outer ends of the frames 131 and support. the forward end of the rudder. At* tached to the forward lend of the rudder, as at 186 is an endless cable 137 extending over revoluble sheaves 138 into the operating compartment, where the cable is attached to a lever 139 and pivotally connected to a bracket 140, carried by the Wall of the operating compartment.. By-simply shifting the lever 139 the rudder can be swung in a desired direction. A

An airship designed forI 'war purposes.- ln Fig. 3 of the drawings, I have shown an airship constructed along the lines of the airship just described, with these exceptions. The intermediate planes are dispensed with and the airship made upon a smaller scale, With the main frame thereof provided with depending supports 141 for a plurality of alternately arranged air ballast bags or ballonnets v142, these bags 'being arranged so that air or gas can be exhausted from the bags to maintain the equilibrium of the airship and its elevation in the air when bombs, torpedoes or other `ex'plpsives are drop ed from the airship, thus preventing a sudden flight or elevation. of the airship when bombs or other matter is thrown overboard. Instead of separate passenger compartments, the depending su port `141 is provided with a central longitui inal frame 143 for a suitable compartment adapted to contain the officers and crew of the airship. It isin connection with this; type of airship that War vessels and fortifications can be destroyed by dropping bombs or torpedoes holding powerful explosives, and arrangements can be made whereby the airship can be lowered and propelled at a great speed over the war ship or fortification, and simultaneously release a bomb or torpedo and Sufficient air from the. airship to compensate for the weight of the bomb or torpedo. This canbe accomplished by either releasing air from the buoyancy bags pr ballonnets 142 or in the case of emergency from some of the hallonnets of the main frame through the medium ofa rip-cord or similar means. The aim in view in connection `with this type of airship is simply to maintain the equilibrium of the same after bombs or torpedoes have been discharged.

From the foregoing it will be observed that by the novel arrangement of the planes, propellers, ballast tanks and balancing devices that the flight, ofthe airshlp can be easily controlled. In some instances, the propellers 130 and ther planes can coperate in moving the airship forward, particularly when maneuverin in the'face of a strong air current, and w en travelin with the air current the planes can be sole y relied u on pro 11ers 119 to ether with the rud positivel contro the movement of the airshi to t e riglit or tothe left, while the propel ers 108 and the ballast tanks will control the ascent and descent of the airship. Thron h the medium of these various operating devices the airship can be maneuvered in an desired direction and turned around practically within its own len li. The planes arranged at the sides of t e airship assist materially in, handlin an airship of such great dimensions besi es redcin the amount of ower ordinarily carried y a for raising and lowering the airshipl. l er wr dirigible bal oon for operating and controllin' the balloon.

, n the large type of airship where the o eratng compartments are separated, telep onic communications can be established whereby the airshipcan be commanded by one oilicer, y
